Pulmonary edema that isn't caused by increased pressures in your heart is called noncardiogenic pulmonary edema. In this condition, fluid may leak from the capillaries in your lungs' air sacs because the capillaries themselves become more permeable or leaky, even without the buildup of back pressure from your heart.
So in other words, ambulatory medical care is a term for almost all of the medical appointments and treatments people receive regularly.
Ambulatory strictly means the ability to walk but in the context of surgery, it refers to patients who are able to leave the hospital the same day as the surgery, without being admitted. Ambulatory surgery is referred to by other names, commonly called minimally invasive surgery, outpatient surgery or same day surgery.
